Application filed March 31, 1926. Serial No. 98,672.

This invention `relatcs to the art of work- Vthiekness of the glass Sheet without interrupting the operation of the apparatus-while the glass sheet is passing` through the 'machine; and further, the provision in such 'a machine of aZ unit control mechanism for I have illustrated niy invention in'the accompanymg drawlngs 111 whlch i Fig 1 is a side elevation of mynew sheet-V glass forming machine; w

F1g-2 1s 'a Vplan view thereof; Flg. y3 isan end elevatlon of'the machine;

' p Figs. 4-10 are detail viewspof the adjusting Inechanism; `and p r Fig. 1111S a side elevation fof a machine withunitary control` for' adjusting'` the 'rolls thereof.

- 'In the drawings, 1 is aV table'vonzwhich `molten glass is Iplaced to `bef-formed 'into sheet-glass. Above the tablev '1 a formin'g 1roll2, a Wire setting roll 8,.and a finish'in'g roll V4, togetherwith eccentricV mech'an'ism forregula-ting the position of said rolls,

Vwhich -mech'anism will be herein'after desoribed 111, detall, are all mounted' on a sultable' carriage consistlngl of 'eight uprlght plates 5, 5,5, 5, .and 6, 6,56, 6. Four of the plates 5, 5, and`6', 6, are mounted on onci'side Vof the table 1 and the other'four plates 5, 5,

and/6, 6, are'fmounted on'y the other side of vsaid table, the 'four sets being secured together, two= and two inparallel, with-an intervening space between'them by separators landibolts', asindieated at 7, 7, 7. The four sets of upright plates 5, '5, and 6, 6, are

further joined together by bolted Separator shafts shown at 8, 8, 8, 8, extending across .the table' 1' and the whole carriage mechanism is mounted on eight rollers 9, 9, four on each Side of the carriage and traveling,

r shown).

respectively, on the'opposite edges ofV the table 1. v

The roll 2 is provided with trunnions, 10, 10, one on each side thereof, which pass through the side-walls 6, 6, ofthe carriage and on the ends of said trunnions are gears` 11, 11, for engagement with the source of power suchas a link belt silent chain (not Eccentric sleeve bearings, 12,12,

vare provided, one for each of said trunnions,

asthey pass through the side-walls, and vthe said eecentric sle'eves` are mounted in close fitting holes in the side-walls 6, 6. It will be apparent, .from the construction just deseribed, that a tmovementz of the eecentric sleeves 12, 12, in unison will raise or lower the trunnions 10, 10, and varythe distance between the forming roll and the table 1.

'In order; that .the desired adjustment may be madeeffectively, I have `provided. gear inechanism for turnlng the eccentric sleeves andsuitable looking mechanism'for maintainmg the whole apparatus at the desred `point of adjustmentTo this end, ring gears. 13, 13 .are keyed asindicated at X to y the outer edge and surface of the eccentricsi 12, 12, and the teeth of the said gears 18', 13, mesh with the teeth of two gears, 14, 14, leyed on` opposite ends of a shaft 15. A calibrated dial and lock gear 16 is mounted 17 engages the teeth of said gear 16 and is held in locked position' by a bolt 18. The roll 3 has suitable Wire setting ridges on its outer face and the rolls and 4 are provided with supporting and adjustment mechanism .similar to that desoribed in connection with the roll 2. A suitable source of power 'for driving the rolls 2, 3 and-4 is indicated at 19 4and connected to the gear 11, 11a, llb, by a link belt Chain (not shown).

In operation, when' it is desired to set the roll .2 a suitable distance from the table V1 to produce a glass' sheet of desred thickness, the dial gear 16 is turned to the corre- ,sponding` calibrated Vmeasurement thereon,

the rotation of the said gear 16 causing the rotation of the gears 14, 14, mounted on the /shaft' 15, which in turn .cause the rotation of the gears 13, 18, and the latter, being keyed to the eccentrics 12, 12, cause said eccentrics to turn in unison about the trunnions 10, 10, thereby raising or'lowering the forming roll the distance from the table l1 indicated on the calibrated dial 16. The lock bar 17 is thenbrought forward until -p on the end of the shaft 15 and a lock bar the teeth thereon engage the teeth on the gear 16 in line With the end of said bar, and the bolt 18 screWed home thus looking the mechanisin in the desired position.

The Wire setting roll 3 is adjusted by turning the dial. gear 16 which movement is transmitted to the eccentric 12*L through the gears 13a and 14a, and in .this instancc, the adjustment is such that the Wire setting` ridges on the roll 3 Will set the Wire the required distance into the glass sheet. The finishing roll 4 is set by turning dial gear 16, the gears 14D, 13h and the eccentric sleere 12b in the inanner described in connection AWith rolls 2 and 3, the roll 4 being adjusted Ato give the desired thickness in the finished sheet.

With the rolls 2, 3 and 4 all adjusted in position and rotating, the table 1 is draWn back int-o position to the right of the sheet forming rolls shown in Figure 1, said table being driven backWard and forward alternately by a rack andpinion mechanism conventionally indicated at 20 and the whole sheet forming structure is supported on stanchions 21, 21, and rests on table at Wheels 9 When table is passing back and forward under machine. With the lfront of the table 1 in position to the right of the forming roll 2, the table is started toWard the .roll and the molten glass poured on the front end of the table. The table and the molten glass travelforWard toward the roll 2 and the glass is fiatten'ed out in sheet form. The formed sheet then passes to the Wire setting roll 3, the Wire is fed tov the top of the sheet and the ridges on said roll extending into the glass and setting the Wire at the required distance therein, the glass displaced by the ridges being forced up into the grooves between successiveridges. After passing through the Wire setting roll, the glass sheet passes under the lfinishing roll 4 Which flattens out the glass ridges produced by the Wire setting roll 3 and the finished sheet is passed on to a receiving mechanism therefor. The driving niechanism 20 is 'thereaft-er reversed, the table draWn back to the vinitial position, and the steps above described repeated.

VVhile I have described my neW machine in connection With the production of Wireglass, the manufacture of plain sheet glass can be carried on by the use of the forming roll 2 alone, in Which case the Wire setting roll 3 and the finishing roll 4 Will be dispensed With; or lbe raised out of contact With the passing sheet; or'the Wire setting roll 3 is raised the required distance and the formi'ng roll 2 and the finishing roll 4 are adjusted to form and finish a sheet of the required diameter; and, .furtheig the said forming machine in any of the above described embodiments, is useful in connect-ion With a continuously traveling table,

such as a Caterpillar structure or a roll, supplied from a continuous source of molten glass or from overlapping pourmgs, or the carriage mechanism may be driven along a stationary table of great length by connectthickness are produced, Without interrupt-` ing the operation of the machine or of the process and While the glass` sheet is passmg through the machine, a change from one thickness to another being accomplished byl unlocking the bar 17 in the. case of plain glass and turning by hand the dial and lock gear 16 to the point indicating the thickncss next desired, the turning of said gear 1G raises or loWers the roll 2 as above described. Then Wire glass is being made, similar adjustments are made on the rolls 2, 3 and 4 successively, but preferably simultaneously, as by three operators, one at each roll, to produce sheets eontinuously of various diameters or thicknesses. In this Way waste' incident to the changing of the thickness of the Wire glass passing through the machine is reduced to a minimum. i

In the appartus shown in Fig. 11 the ad- Vjustment of the eccentrics of rolls 2, 3 and 4 is accomphshed simultaneously by one operator by means of a unit control mechanism for initially setting the machine or for changing from one thickness to another While the glass sheet is passing through the machine. In this structure Worm gear 22, 22a and 22b are keyed to the eccentric sleeves 12, 121 and 12b of the'respective rolls 2, 3 and 4 on each side of the machine, and Worms, 23, 23a and 23b 'are provided for the Worm gears 22, 22a and 22h. The Worms 23, 23a and 23 on each side of the machine are mounted on shafts 24, 24, provided With uni- ,versal joints, 25, 25, and the two Ashafts 24 are connected through gears 26 and 27 and cross shaft, 28. It folloWs, then, that va movement of one shaft 24 as by the rotation of a Wheel, 29, causes all the aforementioned interconnected shafts andZ gears, Worms, Worm gears and cross shafts to cooperate to move in unison all the eccentric sleeves 12, 12a and 12b on both sides of the machine and raise or lower the rolls 2, 3 and 4 Simulltaneously the desired distance from the table 1. It Will be understood that the eccentric sleeves 12a of the Wire setting roll 3 have a throw in adjustment of only half that of the eccentric sleeves 12 and 12b of the rolls 2 and 4 and hence the Wire netting is maintamed in the center of the glass sheet of any thickness to which the machine is adjusted. A crane 30 is provided for lifting and loWering the carriage containing the rolls 3 and 4 out of and into operative relation With the glass sheet passing through the machine yio when it is desired to change .over from Wire glass to plain glass and Vice versa in either type of machine shown in the drawings. The crane30 is particularly useful in connection With the type of machine shown in Figure 11, Where the rolls 2, 3 and 4 are linked togetl'ierthrough the'unitary control mechanism, as the ealibrated relation of the rolls to each other is maintained at all times. Thus, With the rolls 8 and 4 raised by the erane 30, out of contact With the glass sheet, the thickness of the plain glass sheet being made by the roll 2 may be changed a number of:ti1nes, the rolls 3 and 4: being adjusted each time through the mechanism act-uated bythe wheel 29, or a dial gear, and When it is desired to change over to Wire glass, it is only necessary to start to feed 'the Wire netting to the glass sheet and lower the rolls 3 and 4 to the position of rest on the table 1.
